This powerball makes my wrist and forearm stronger, its something you cannot achieve at gym

This powerball makes my wrist stronger, I had less wrist pain while I play badminton

at first it is hard to keep it going, but it quickly turns into a powerful force that I need to switch from one hand to the other as my strength increases

I love to spin the powerball to the top speed, and listen to the sound from the spinning

Its great fun to play with it and at the same time it strengthen my wrist
